FNB Smart Device refuses to repair my cellphone!!!

I bought my cellphone from FNB Smart Devices 2 months ago and it just went blank and stopped working. I contacted them and was told by an agent to take my cellphone to SSS cellular where it would get repaired as it had a 2 year warranty. A week later I received a quotation from SSS cellular stating that I need to pay R4200 for my cellphone to be repaired and the reason was PHYSICAL ABUSE. I can confidently state that I have never dropped the phone and the screen has no cracks yet it was apparently Physically abused!!!!<br> <br> I am extremely disappointed with fnb considering that I have been a loyal customer. I am very angry as I had to constantly call and ask for updates. They are still debiting for a cellphone which I don't even have and I am told I would need to pay the full value of the phone should I cancel and oh everytime I call the center it just messes up with my airtime.<br> <br> I am beyond disappointed shame!!!!
